Are the AR uppers for the .223-.243 wssm any good? Are they worth the money? The performance of the little cartridges are amazing, and it would be cool to convert an AR.Here http://www.impactguns.com/store/OLY-PCR8223WSSM.html and here http://www.accuracysystemsinc.com/ar15_conversion.html is where I saw them.

In the west to go from 250 to 300 yds, to 450 & 500 yds when needed makes all the design propaganda fade in light of performance that works. Dont think of it as a replacement for the .223, Its not intended to be, just think for a moment. Lightning was'nt meant for electricity but because of it we now have it. The WSSM line in an AR platform gives you lightning when you want it. The .223 was designed for a purpose, and now that purpose has been expanded, some say beyond its capability. But it has served its purpose very well. The manufactures study design to exploits of destruction before they can bring products to market. Just because all manufactures have'nt expanded thier current lineup to include the WSSM format does'nt mean they wont. It means they have had other points of intrest for thier R&D departments first, like M-4 production or .308 cal production. Do not be mistaken Winchester did'nt leave any performance out of this case design, and because it fits in a standard size AR, means they will have to look at its merits after all or again be lagging behind in the design curve that fills thier orders. One last comment, custom designers have always lead new frontiers best, they are a good place to start your questions of interest. No disrespect intended.

Good for what they are intended for...shooting longer range with a base platform. Don't discount creativity. The idea of staying locked into a 5.56/223 platform is very, very small minded. I'd hate to have seen that thinking when the Stoner came out with it. Oh wait....it was there. The rifle has proven itself that thinking outside the box can yield beautiful creations. And, likewise, thinking beyond the perceived capabilities of a platform can sometimes open up new possibilities. AR-15 -> AR-10 -> Tubb 2000. Pretty nice progression.

Thats a nice progression. The problems come up when folks start with the AR-15 and hold onto the AR-15. Too many think they can just slap an upper with a chamber for a different caliber and have the same reliability. That would be like expecting an AR-10 to run chambered in 6.5x284, thats what the T2K is for

Its the singer not the song. Spend your money on practice ammo. www.adcofirearms.com

This wasnt meant to make anyone mad, just wanted to make a target gun that would shoot the .223-.243 wssm with semi-auto. The ar-15 is a gun the would adapt to do that easily, and I like that I could change back to .223rem quickly. Didnt mean to make anyone angry, just asking a question.

The WSSM line on the AR-15 platform has proven to be very reliable. Of course it doesn't have the decades of history that the 5.56 does but with the 100 + WSSM uppers that I have put out, reliability has never been an issue.

I don't think the WSSM on the AR-15 platform will ever be wildly popular, but the following it does have is quite loyal. Big-game hunting, predator hunting and long range varmint hunting is a perfect spot for it. Flatter shooting , lighter and less expensive than an AR-10 and you can buy the ammunition at Wal-Mart.
